This is a fast-growing tree with fragrant spring flowers. Its delicate, open silhouette lets grass grow underneath. Tiny leaflets turn yellow or yellow-green in fall. The honeylocust is pollution, salt and drought tolerant and adapts to a wide range of soils. It prefers full sun and can grow up to 70 feet with a 50 foot spread. This tree has been overplanted in the valley and can suffer in the summer heat especially when infested with spider mites.
